A

proper, cartilage, bone, and blood

40
Q

what are the functions of connective tissue?

A

binding and supporting, protecting, insulation, storing fuel, and transporting substances

41
Q

why are connective tissues grouped together?

A

they all develop from the same type of embryonic tissue known as mesenchyme, the have varying degrees of vascularity, have extracellular matrix

A

gellike ground substances; has all three fibers

51
Q

what is the function of areolar tissue?

A

serves as packing material for organs

52
Q

where is areolar tissue located?

A

under epithelial tissues and around organs

53
Q

tendons and ligaments

61
Q

what is the function of regular tissue?

A

tendons - connect muscles to bones muscles - ligaments connect bones to bones

Q

what type of matrix does irregular tissue have?

A

randomly arranged collagen fibers

63
Q

what is the function of irregular tissue?

A

strong when pulled in many directions

64
Q

high number of elastic fibers

66
Q

what is the function of elastic tissue?

A

allows tissue to bounce back after stretching
